Sublinear time approximation of the cost of a metric k-nearest neighbor graph

A Czumaj, C Sohler - Proceedings of the Fourteenth Annual ACM-SIAM …, 2020 - SIAM
Let (X, d) be an n-point metric space. We assume that (X, d) is given in the distance oracle
model, that is, X={1,…, n} and for every pair of points x, y from X we can query their distance …

Sublinear Time Approximation of the Cost of a Metric -Nearest Neighbor Graph

A Czumaj, C Sohler - SIAM Journal on Computing, 2024 - SIAM
Let be an-point metric space. We assume that is given in the distance oracle model, that is,
and for every pair of points from we can query their distance in constant time. A-nearest …
